Lead Exposure

it using systems such as gypsum wallboard, plywood paneling, and aluminum, vinyl, or wood exterior siding.
Floors coated with lead-based paint can be covered using vinyl tile or linoleum.
The building owner or other responsible person should oversee the custodial and maintenance staffs and
contractors during all activities involving enclosed or encapsulated lead-based paint. This will minimize the
potential for an inadvertent lead release during maintenance, renovation, or demolition.
SUBSTITUTION
Choose materials and chemicals that do not contain lead for construction projects. Among the
options are:
•
•
•
•
•
Use zinc-containing primers covered by an epoxy intermediate coat and polyurethane topcoat
instead of lead-containing coatings
Substitute mobile hydraulic shears for torch cutting under certain circumstances
Consider surface preparation equipment such as needle guns with multiple reciprocating needles
completely enclosed within an adjustable shroud, instead of abrasive blasting under certain
conditions. (The shroud captures dust and debris at the cutting edge and can be equipped with a
HEPA vacuum filtration with a self-drumming feature.)
One such commercial unit can remove lead-based paint from flat steel and concrete surfaces,
outside edges, inside corners, and pipes.
Choose chemical strippers in lieu of hand scraping with a heat gun for work on building exteriors,
surfaces involving carvings or molding, or intricate iron work. Chemical removal generates less
airborne lead dust. (Be aware, however, that these strippers themselves can be hazardous and
that the employer must review the safety data sheets (SDSs) for these stripping agents to obtain
information on their hazards.)
COMPONENT REPLACEMENT
Replace lead-based painted building components such as windows, doors, and trim with new components free
of lead-containing paint. Another option is to remove the paint off site and then repaint the components with
zinc-based paint before replacing them.
PROCESS OR EQUIPMENT MODIFICATION
When applying lead paints or other lead-containing coatings, use a brush or roller rather than a sprayer. This
application method introduces little or no paint mist into the air to present a lead inhalation hazard. (Note that
there is a ban on the use of lead-based paint in residential housing.)
Use non-silica-containing abrasives such as steel or iron shot/ grit sand instead of sand in abrasive blasting
operations when practical. The free silica portion of the dust presents a respiratory health hazard.
